G1.Assassin Overclock

[Av8tortoo]

Hi

Just want to drop in let everyone know I have started my overclock of the G1.Assassin.

I haven't overclocked anything before to an extreme so this is my first shot at it. (Where is the turbo button)

(kidding).

Just everyone a heads up and a quick review of the beast...

Gigabytes G1.Assassin

990X

12 GB Corsair 1600 DDR3

2 P128 Corsair SSD (raid 0)

XSPC Rasa 750

I am starting to look for the best base clock (BCLK) now.

I have the BIOS set up as the the following: (please if you have any pointers or suggestions let me know)



If you can see the attachement its showing how I am raising the BCLK to test.

Started with:

BCLK: 150

Multiplyer: 12

Memory Clock: 6

CPU Volts: 1.24375

DRAM Volts: 1.584

QPI Clock: 36

UnCore: 18

IOH Core Volts: 1.18 (two video cards)

QPI/VTT: 1.215

With those setting I have made it to a BCLK of 190 so far.

BCLK 200 the board is starting to get picky about the volts. Had to raise VTT to 1.255

I am running 3 passes of IntelBurnTest Custom with 10000 RAM and Prime95 10 mins. With the tests the temperature have not gone above 42C with a 21C room temp. Not 100% sure that is enough stress right now, but trying to get in the ballpark of near max and then fine tune. I know from reading and watching Tom, he got a BCLK of 220 on the 990X, so I am shooting for that, and also a stable OC of 4.8 to 5 Ghz.

And a side note: TTL Wow, thanks for the info and helpful advice you show in your videos and reviews, great work, keep it UP.

As you can see this is all a work in progress, and I'll be adding to this post as the overclocking progresses

cool

keep us informed

I see a brick wall in front of me, rushing faster and faster then a volt, of 1.4 VTT.

I must be doing something wrong or the CPU was made on a Friday at 16:49.

BCLK: 220

Multiplier: 12

Memory Clock: 6

CPU Volts: 1.25656

DRAM Volts: 1.584

QPI Clock: 36

UnCore: 18

IOH Core Volts: 1.18 (two video cards)

QPI/VTT: 1.395

Seems to be the Max, I am willing to go from reading that Intel's absolute maximum for the VTT voltage is 1.4V.

Prime95 passed for 10 mins running at 1.375V for the VTT, but the system locked up using IntelBurnTest.

I do have a few questions now. Tom if you are reading this, what was the maximum VTT you used during the building and clocking of the Assassin? Or if anyone else can answer that or give advice I would be very thankful.

Also, Did you have on Load-Line Calibration, and which setting was used? I am using Standard now (Intel specifications) Which disable LLC and sets VDroop following Intel Spec.

The other choices are: Level 1 and Level 2. Level 1 - Enables LLC and slight adjusts VDroop. Level 2 - Enables LLC and moderately adjusts VDroop.

On CPUz, the Core Voltage is showing 1.2 to 1.216 volts, I am wondering if that's because I don't have on LLC or I missed a power saving feature in the BIOS. Then on the screen shot of have seen on CPUz where the "Multiplier" is it shows only X12 but on the screen shots I have seen it show X12.0 (12 - 24), why?

Well the Assassin passed the IntelBurnTest that time, running Prime95 now, with the above settings.

CPU Z is showing 1.2 something volts because that is what your CPU Voltage is set to. You only raised the voltage of your QPI, which is also called VTT, that is not your CPU voltage ( sometimes called Vcore)

 

[Hay11Mac]

That is one beast of a system.......

We need pics of your rig

I understand that finding the BCLK is raising the QPI/VTT in the BIOS. I was thinking I was taking a shortcut by limited the Vcore to 1.25656 volts.

From the screen shot on the Assassin built max BCLK.

It reported, it passed the IntelBurnTest for 3 passes, then it passed Prime95 for 10 mins. Then I was running Prime95 over night but it locked the system at 1.4 hours at the 1.25656 volts.

So what I have done this morning is set the Vcore back to "AUTO" and am running the tests again.

Just ran IntelBurnTest for 3 passes it passed. Now running Prime95

The setting in the BIOS:

BCLK - 220

Multi - 12

Memory CK - 6

Vcore - AUTO CPUz is showing 1.344 Volts

DRAM Volts - 1.584

QPI Clock - 36

UnCore - 18

IOH Core Volts - 1.18

QPI/VTT Volts - 1.395

QPI Link 3960

Memory Speed 660

GHz - 2.64

With Prime95 and IBT running (not at the same time) the max temp was 51C with a room temp of 20C.

If Prime95 passes for the hour check (which it should because it did last night) I am going to go for a 230 BLCK at 1.395 VTT.

Do you guys agree that 1.4 VTT should be the max according to Intel specs or have any of you gone above 1.4 VTT?

Here are some pictures of the computer.

I am using my older Video cards in the system, waiting on the Nvidia GTX 590s to come out of hiding for inspection before I upgrade.

Looks good Av8tortoo, the more I see that water cooling kit the more I want it

I need to get a new case and graphics card first though.

 

[Aurus_OC]

Looks really nice! You should get that horsepower folding

I have my work computer folding for the team now.

It seems, that 220 BLCK is it, the system WILL NOT BOOT with anything Higher, just like what Tom ran into, I am guessing.

I ran Prime 95 with the setting above for 2 hours. Everything passed.

I lowered the QPI/VTT setting to 1.335 volts and trying to run the tests now. Time to clean up the house etc while it running and maybe see a movie later today while Prime is running. If you guys see Battle: Los Angles. LOL it was filmed about 1/2 mile from my house in SHREVEPORT, LOUISIANA.

Looks like a good overclock to me. Like you did lowering the voltages untill you reach a minimum is the way to go now. Great to have you on the folding team!

get folding dude - and put that rig to some great use.

we cannot help them in japan, but can help research cures for alot of diseases and cancers

Welcome to the team mate.

You should have tried to get on camera whilst they were filming BLA, made a mad dash for it through the set or something

Matey you just earned all my respect

can't say how much i appreciated this

I from day one have my fingers crossed !~!

Awesome rig m8.... Love the motherboard and the water-cooling loops...... Nice

Now I am not sure what to do now. With the memory been reading that there is a very slight advantage to overclocking the memory, but a better day to day operation if you tighten the timings on them, what do you guys think?

 

[Av8tortoo]

This post is a MAJOR sounding board for me right now, typing thoughts and actions. In other words it will be nuts

Moving into unknown areas for me with Memory overclocking or tighting the timmings.

From what I have been reading: Has got me lost in the forest of dead trees from the papers printed out and looked over.

I am trying to over clock my memory in the system. But have gave up until I understand it better.

What I am doing now is lowering the Memory multiplier to keep the memory near stock speeds. But this is what have tried...

When I tried to increase the memory speeds by using a 10X multiplier and a BCLK of 180. So the speed would be 1800MHz., with the timmings of 9,9,9,24 and the DRAM volts of 1.5 and 1.6. Got a host of errors and strange things going on. From no sound to the keyboard not working.

With those setting I could not even run Prime95 for 2 seconds before the errors would shut it down.

The system is setup right now as:

BCLK - 190

CPU Clock Ratio - 12X

QPI CLock - x36

SPD - 8.0

XMP - Profile1

Preformance Enhance - Standard

DRAM Timing - Expert (not even close to that now.. lol )

Memory timings 9,9,9,24

CPU Vcore - Auto (CPUz shows 1.376)

QPI/Vtt - 1.395V

IOH Core - 1.18V

DRAM voltage - 1.5V

The memory has made it to 1680 Mhz. (not much over stock) Using the BCLK of 210 and all the stock settings, and speed of 8.

Nice one Av8tortoo that's awesome.
